Sacerdotal state
A sacerdotal state is a state whose head is also an ecclesiastical leader designated by a religious body. An example of this kind of state is the Vatican City: its heads of state, the popes of the Catholic Church, have governed papal lands distinct from secular authority since the establishment of the Papal States in the 8th century AD. Andorra operates under a semi-sacerdotal system, as one of its co-heads of state is the bishop of Urgell, while the other is the head of state of France.
